Successfully manufactured super accurate quantum compass, superior to GPS

Its full name is "independent quantum accelerometer".

GPS positioning is one of the key elements that appear in many modern technologies of this century. But users do not always connect to GPS: high houses, deep tunnels can block or interrupt GPS signals sent from satellites. From that point on, GPS can be blocked in many ways.

Equipment with the name "independent quantum accelerometer".

To overcome that, scientists go beyond making a signal that is not blocked, they create a new navigation device . Researchers at Imperial College London successfully designed a quantum compass, navigating without a satellite. The device is called "standalone quantum accelerometer" that is small enough to be carried here, to be released to the public at the International Quantum Technology Exhibition.

By new quantum accelerometer, the device's accuracy is extremely high.

The accelerometer, true to its name, is a tool to measure the speed of an object over time , even in your smartphone. By information obtained from location and speed, the system can calculate the position of the object. With conventional accelerometers, the accuracy will decrease over time if it is not maintained with a reference object.

By new quantum accelerometer, the device's accuracy is extremely high. By measuring the motion of ultracold atoms - the state that makes a particle represent quantum properties, at the particle and wave states at the same time, the system achieves high accuracy. The waves of atoms are affected by acceleration, measuring the deflection of the waves that will produce the atomic motion. " Accurate to the atomic level" means that.

This device can be installed on boats, trains, airplanes or any large size vehicles.

Although it is not possible to fit into a pocket like a normal compass, this device can be installed on boats, trains, airplanes or any large size vehicles. When there is no GPS, the quantum factor will tell the vehicle operator its exact location.

When we build a powerful laser system - which keeps atoms cold enough to show quantum properties to measure - and compact, then we will have a pocket quantum compass.
